Note 6 — Chapter VII · The Relations of The Grateful Dead to The Spendthrift Knight, The Two Friends, and The Thankful Beasts.
Reading edition
As to the way by which it entered the cycle, one must conclude that it was afloat in Europe before the thirteenth century,6 and furnished a very natural opening for a tale in which a youth goes into the world to seek adventure or profit. Were a lady to be won by the help of the ghost, it would magnify the hero’s part, if he were given an opportunity to take some very direct share in the wooing. So in the group of which Richars and Sir Amadas are members the new theme supplied the means of winning a lady, which would otherwise be lacking. In Oliver and Lope de Vega it has perhaps supplanted the ransom of a maiden, which is the trait to be expected, if they are rightly placed among the variants of the type The Grateful Dead + The Ransomed Woman. It will be noted that in the two Icelandic tales, which conform closely to the type, the tourney does not appear. There seems to be reason, therefore, for supposing that the new material touched our central theme at least twice, combining with the prototype of the Amadas group and of the Icelandic folk-stories. The authors of Oliver and Treu Heinrich may have adopted it consciously, and so these variants should be left out of account.
